Foods high in probiotics that contribute to gut health include yogurt, kefir, sauerkraut, tempeh, kimchi, and miso. These foods contain beneficial bacteria that help maintain a balanced gut microbiome, which enhances digestion and boosts the immune system. Regular consumption of probiotic-rich foods can improve gut flora diversity, leading to better nutrient absorption and improved overall health. It's important to combine probiotics with a fiber-rich diet to support the growth of these beneficial microbes.
